Question

Before starting this problem, review Conceptual Example 7. The force vector A a has a magnitude of 75.0 newtons (N) and points due east. The force vector B has a magnitude of 139 N and points 74.1 degree north of east. Find the (a) magnitude and (b) direction of A - B. (Give the direction as a positive angle with respect to due east). Find the (c) magnitude and (d) direction of B - A. (Give the direction as a positive angle with respect to due west).
